Abelia plant named ‘SRPabeper’

ABSTRACT

A new and distinct variety of  Abelia  plant, herein referred to by its cultivar name, ‘SRPabeper’, is provided which forms on a substantially continuous basis attractive white colored flowers. Attractive, tri-colored orange, yellow, and green colored foliage is formed. The growth habit is moderately vigorous and compact and well-branched. The new variety is well suited for providing attractive ornamentation in the landscape.

Botanical/commercial classification:

Latin name—Abelia hybrid.

Varietal denomination—‘SRPabeper’.

SUMMARY OF THE INVENTION

The new variety of Abelia hybrida plant originated in a controlled breeding program in West Grove, Pa. during June, 2010. The objective of the breeding program was the development of Abelia cultivars with large flowers, attractive foliage coloration, and improved hardiness. The new cultivar was created by cross-pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the Abelia chinensis (non-patented in the United States). The male parent (i.e., the pollen parent) was the Abelia x grandiflora ‘Kaleidoscope’ variety (U.S. Plant Pat. No. 16,988).

The parentage of the new variety can be summarized as follows: Abelia chinensis x ‘Kaleidoscope’

The new cultivar was discovered and selected as a single flowering plant from the progeny resulting from the above pollination during September, 2013 in a controlled environment in West Grove, Pa. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Abelia plant of the present invention:

-   -   (a) substantially continuously forms white colored flowers,     -   (b) displays tri-colored foliage colored orange, yellow, and         green,     -   (c) exhibits a moderately vigorous and compact and well-branched         growth habit, and     -   (d) is well suited for providing attractive ornamentation.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the Abelia chinensis variety (i.e., the seed parent) displays medium green colored foliage and an upright to rounded growth habit, while the new variety provides tri-colored foliage colored orange, yellow, and green and displays compact and well-branched growth habit. The ‘Kaleidoscope’ variety (i.e., the pollen parent) displays dark and light yellow-green variegated foliage and a spreading to broadly upright growth habit, while the new variety provides tri-colored foliage colored orange, yellow, and green and displays compact and well-branched growth habit.

The new variety can also be distinguished from other similar varieties that are commercially available. For instance, the new variety of the present invention can readily be distinguished from the ‘Abelops’ variety (U.S. Plant Pat. No. 20,961), as the new cultivar displays a more compact growth habit than the ‘Abelops’ variety and the foliage of the new variety is orange, yellow, and green tri-colored, whereas the ‘Abelops’ variety displays dark and light yellow-green variegated foliage edge.

The new variety has been found to undergo asexual reproduction by a number of routes, including terminal stem cuttings. Asexual propagation by the above-mentioned techniques in West Grove, Pa. since September 2013 has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘SRPabeper’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant and plant parts of the new variety. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘SRPabeper’ variety. The plants were grown in one-gallon pots for approximately five months outside at West Grove, Pa. Plants were pinched once after transplant.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Color Chart), 2015 edition, London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The color values were determined in September 2017 under natural light conditions in West Grove, Pa. The description is based on the observation of plants produced from cuttings from stock plants and grown in one-gallon containers for approximately five months in an outdoor nursery in West Grove, Pa. Plants were pinched once after transplant.
